How are workers coping with the heatwave?

As temperatures continue to soar, we have spoken to workers across the south of England to find out how they are coping in the extreme heat.

It is the third day of a red weather warning for parts of Hampshire, Berkshire and Oxfordshire, with an amber alert for a wider area until midnight.

The NHS in Hampshire alongside hospitals in Southampton and Portsmouth and South Central Ambulance Service have declared critical incidents as the heat impacts on buildings and equipment.

How are workers across the region coping in this weather?

Over the next week, the Great Court at Blenheim Palace in Woodstock will be graced by names that people in Oxfordshire and Berkshire normally have to travel hours to see - Pete Tong, Alanis Morissette, Teddy Swims, Katy Perry and Michael Bublé.

This year, the event has been brought in-house for the first time after Nocturne Live Oxfordshire revealed that, after 10 years, it would no longer be staging its outdoor music festival at the stately home.

With temperatures hitting 33 and 34C this week, labourers told the BBC the stage build has been challenging, with JCBs conking out and extra staff brought in.

Heather Carter, managing director of Blenheim Palace, says they are still on track to be ready.

"We've had a lot of other things happen across the estate," she said.

"Freezers going down, air conditioning not working, so we've made adjustments for everybody.

"The chaps building the stage and the seating, they were starting at five o'clock in the morning or even earlier, and they're taking two or three hours off in the middle of the day and coming in at night to finish off - continental style.

"So we've adapted."

Samuel Szymczyk, an insulation specialist based in Reading, told BBC Radio Berkshire he has seen a loft reach 51C during the heatwave.

"There's days like yesterday and today [Friday] we were meant to be doing a couple of houses... we said to the customer it's unbearable... we're fortunate to be able to move it into the next week, but not everyone can," he said.

He said by the time he came out of one loft on Tuesday morning, "I looked like I'd come out of a sauna".

He stressed the importance of keeping a "sensible head" and taking regular water breaks.

"You can't expect to be cracking on at the same tempo as you would when it's normal temperature... it's a balance."

Mark Worboys, a Broadstone-based tree surgeon who works all around Dorset, told BBC Radio Solent: "I think anyone who works outside, there's no getting away from it, you can't move the trees or the hedges to a nice shady spot, so you've just got to deal with it, unfortunately.

"When the weather gets this hot, it's picking the right job for the right day.

"Wearing our normal chainsaw-proof trousers and boots and the helmet and everything, it's pretty dangerous, you're up at heights with chainsaws and the risk of injury if you're suffering from a bit of heat stroke or dehydration - it's very difficult."

Worboys, who has been working outside for more than 30 years, said he is "very fortunate" to have "some great customers" who provide cold drinks.

There's no law in the UK that says a given temperature is too hot or too cold to work.

But guidance from the Health and Safety Executive (HSE), says employers must stick to health and safety at work law, which includes keeping temperatures at a "comfortable" level, and "providing clean and fresh air".
